A deliciously seamless bottom that is totally invisible under clothes, moisture wicking and breathably soft for days on the run...it shouldn't be rocket science. Or should it? KnixWear's innovative patented anti-microbial Freshfix fabric stretches directionally to allow for invisibly slinky smoothness and is paired with a quick-dry cotton gusset for all-natural comfort. Perfect for everyday, ideal for travel, an absolute necessity for clingy or sheer bottoms. Now that's what we call an upgrade.
